Nothing ruins a good trip like a bout of diarrhoea, nausea, exhaustion, and a fever. Water borne illness caused by nasty water borne bacteria and viruses is one of the leading causes of health problems for travelers. It can have serious immediate consequences and after-effects for months.
There are some other water pollutants to consider, such as chemicals and metals that come from poorly maintained water pipes and other sources.
High-risk areas include Central America, most of Africa and Asia and the Middle East. Moderate risk areas include Eastern Europe, Russia, South Africa, Argentina, Chile, and the Caribbean. Even developed countries aren't necessarily risk-free.
Basically if you want to be safe, assume the worst and plan accordingly.
Don 't use local tap water without purifying it in some way, even for brushing your teeth or washing fruits and vegetables. And don't make the mistake of using locally produced ice cubes: Freezing doesn't kill the germs!
Anyone who has traveled will be well aware of the huge problem or plastic bottles littering the countryside, turning pristine bush and beaches into rubbish tips.
Using just 4 bottles a day, a single traveler is likely to throw away over 50 bottles in just a couple of weeks – not a nice legacy to leave your host country.
On average in the US alone, 1500 plastic bottles are used EVERY SECOND. And only a small percentage globally are recycled.
Annually, 8 million metric tonnes of plastic is dumped in the world's oceans. All this plastic eventually ends up in the massive floating garbage patches, including the now infamous "Pacific Garbage Patch" where it breaks down into microplastics which sadly marine life consumes, resulting in a slow agonising death.
Then there's the carbon footprint, the health, and toxicity issues... the list goes on.
But it's not all doom and gloom, there are many ways you can consume local water safely and give the environment a hand at the same time without using bottled water.
If you can avoid plastic bottled water on your travels, you'll be doing yourself and the environment a favor. Start buy grabbing yourself a durable metal or glass bottle, or a reusable hydration bladder.
Here are some other options that are all cost effective, healthy, and environmentally friendly:
A very simple and cost effective option to ensure you kill the bugs which make you sick. However it can become time consuming and finding a place to boil water may be difficult.
Purifying tablets are simple to use, cost effective but can sometimes taste slightly unpleasant. Another factor to consider is that some tablets have a high iodine content and not all purifying tablets are affective against Cryptosporidium, which can give you a bad case of diarrhoea so read the packaging before purchase.
Easy to carry but can be expensive to buy and replace filters plus not all bottles filter out viruses. Some bottles use an iodine filter which can make the water taste like iodine whereas others use carbon filters.
These are a cost effective, portable water purifying option for travelers especially wilderness hikers and campers allowing you to drink directly from a river or stream.
They last around 3 to 5 years depending on frequency of use and will filter out a high percentage of water borne pathogens.
An easy and portable way to kill bugs and sterilise local water. However the downside to UV purifiers is that they can be expensive, do need to be recharged, can be fragile, need replacement parts and won't work on dirty water.
There are many different filter jugs available on the market however they are not suitable for time poor travellers on the go. But jug filtered water tastes fine and it can be a cost effective measure if you are staying put in one destination for a while. Make sure you check out the filter type so you can filter out those nasty bugs and other pollutants.
Many countries around the world are now installing water refill stations in public areas, airports and also at various locations where people hike, rock climb and other outdoor activities which makes it a quick and easy way to get clean drinking water.
In the US, many airports including San Francisco, Denver and Tampa International airports have placed water refill stations throughout for travelers and workers to use.
In Thailand, a water refill station was installed at a well known climbing and caving area in Chiang Mai. The effect was instant with a noticeable reduction in the number of plastic bottles polluting the surrounding environment.
